Technical requirments on the material1)Steel tube:*Carbon steel*Surface of steel tube should be smooth*without any fault such as crack, folding, layering or lap welding *Ovality shoud be less than 1/2 of tolerance of outer diameter*curvature should be less than 1.0mm/m

3)SealNon-contact seal:It is seal and its relative motion parts don't contact, and there is proper clearance seal.Advantage*Almost do not produce friction heat in the work*No wear and tear, especially suitable for high speed and high temperature occasion.*Forming a complex, winding and narrow maze between inner and outer seal part.*The good performance of water-proof and dust-proof.

4)Lubricating oilRolling bearing lubrication purpose is to reduce the bearing internal friction and wear, prevent burning stick.The lubrication effect is as follows.*Reduce the friction and wear*To extend the fatigue life *Discharge the friction heat and cooling*To prevent foreign matter into the bearing internal, or to prevent rust and corrosionETC.
